Members of the family Sphaerolipoviridae have non-enveloped tailless icosahedral virions with a protein -rich internal lipid membrane. The genome is a linear double-stranded DNA of about 30 kbp with inverted terminal repeats and ter-minal proteins. The capsid has a pseudo triangulation T= 28 dextro symmetry and is built of two major capsid protein types. Spike complexes decorate fivefold vertices. Sphaerolipoviruses have a narrow host range and a lytic life cycle, infecting haloarchaea in the class Halobacteria (phylum Euryarchaeota). This is a summary of the International Com-mittee on Taxonomy of Viruses (ICTV) Report on the family Sphaerolipoviridae, which is available at ictv.global/report/ sphaerolipoviridae.
